In Challenge, players take control of a duck. The duck can only move vertically until it reaches the top or bottom of a column, then it can move left to get to the next column.
The columns are intersected by rows. These rows contain creatures that continually go back and forth. Players have to go up and down between these columns while dodging the patrolling creatures. Successfully navigating all the columns in the six minute time limit completes a stage. Completing a stage earns an extra life on top of the six lives the player starts the game with and brings the player to the next stage which has increased difficulty due to more creatures being added.
Challenge is an Action game, developed and published by Funvision, which was released in Europe in 1980. While playing it you will see a Funvision logo on the bottom of the screen. Funvision most likely is the original company for Challenge. When you play the PAL Quelle version you see no logo because it has been erased. When you play the PAL HES version you don't see a logo either, but if you took a hex editor you can clearly see that the Funvision logo is still in the rom. This shows that HES was not the original company.
